HMS Weazel or Weazle was a 16-gun ship-sloop of the Royal Navy, in active service during the War of the Austrian Succession, the Seven Years' War and the American Revolutionary War. Launched in 1745, she remained in British service until 1779 and captured a total of 11 enemy vessels. She was also present, but not actively engaged, at the Second Battle of Cape Finisterre in 1747.

The second battle of Cape Finisterre was a naval encounter fought during the War of the Austrian Succession on 25 October 1747 (N.S.). A British fleet of fourteen ships of the line commanded by Rear-Admiral Edward Hawke intercepted a French convoy of 250 merchant ships, sailing from the Basque Roads in western France to the West Indies and protected by eight ships of the line commanded by Vice Admiral Henri-François des Herbiers.
